The company name "Simple Maps" fooled me - this map is far from "simple". It's comprehensive, easy to use and packed with features!

If you go to the company website, you can create a map with all the latest functionality - zooming in and out of continents, and borders to show all the different countries. Everything seems to be customisable - colours, background transparency, location dot colouring and transparency, clicking through to custom URLs, the list goes on .

All in all, a thoughtful and well build piece of software. Oh, and it's responsive (you just need to tweak a few settings).
